Employing microarray assays, a total of 267 genes were identified that were significantly up- or downregulated in PBMCs of WT-NOD2 patients, compared to healthy donors after challenge with vitamin D (+/-D) and/or a combination (+/-LP) of LPS (lipopolysaccharide) and PGN (peptidoglycan) (p < 0.05; threshold: 2-fold change). For further analysis by real-time PCR, 12 genes with known impact on inflammation and immunity were selected that fulfilled predefined expression criteria. In a larger cohort of patients and controls, a disease-associated expression pattern, with higher transcript levels in vitamin D-treated PBMCs from 5 patients, was observed for three of these genes, CLEC5A (p < 0.030), lysozyme (LYZ; p < 0.047) and TREM1 (p < 0.023). Six genes were found to be expressed in a NOD2- dependent manner (CD101, p < 0.002; CLEC5A, p < 0.020; CXCL5, p < 0.009; IL-24, p < 0.044; ITGB2, p < 0.041; LYZ, p < 0.042). Interestingly, the highest transcript levels were observed in patients with heterozygous NOD2 mutations.

View SamplesMYCN-high and MYCN-low neuroblastoma cells differ in their responses to Doxorubicin treatment. To explain this difference we compared the global trancriptomes of MYCN-high and MYCN-low cells before, during and after treatment. Overall design: MYCN-high cells without doxycyline and MYCN-low cells with doxycycline were treated with 0.1µg/ml Doxorubicin. Transcriptome was measured for the following time points: in untreated cells, in cells which were treated with Doxorubicin for 72 hours, and in cells collected three, eight and fourteen days after Doxorubin washout. Experiment was performed in biological duplicate.

Genomic impact of transient low-dose decitabine treatment on primary AML cells.
Sex, Age, Specimen part, Disease, Treatment
View SamplesAcute myeloid leukemia (AML), and other myeloid malignancies, are frequently treated with hypomethylating agents like decitabine. Alterations in the epigenome, induced by decitabine, are likely to result in gene expression changes. The effects of decitabine have not been systemically studied using primary AML samples.

View SamplesThe objectives of this study were to measure effects of an aspirin intervention on gene expression in normal colonic epithelial and stromal tissue in healthy humans and to determine whether response differed by UGT1A6*2 genotype. We also sought to characterize gene expression differences within colonic tissue microenvironments by identifying genes that were differentially expressed between epithelial and stromal tissue.
